这篇先暂时这么写了……还没来得及设置任何样式

1、客户端

1 import socket,os 2 #创建套接字 3 client = socket.socket() 4 #连接一个套接字地址 5 client.connect(('localhost',9999)) 6 while True: 7     #输入一个DOS或者shell命令 8     cmd = input(">> ").strip() 9     if len(cmd) == 0: continue10     client.send(cmd.encode("utf-8"))11     data_size = client.recv(1024)12     print("返回长度: ",data_size.decode())13     recv_size = 014     recv_data = b''15     #连续接收数据16     while   recv_size != int(data_size.decode()):17         data = client.recv(1024)18         recv_size += len(data)19         recv_data +=data20     else:21         #接收完成，输出结果22         print(recv_data.decode())23         print("recv done...",recv_size)

2、服务器端

1 import socket,os 2 server = socket.socket() 3 #绑定并且监听该端口 4 server.bind(('localhost',9999)) 5 server.listen() 6  7 while True: 8     #接收一个客户端的连接 9     conn, addr = server.accept()10     print("新连接",addr)11     while True:12         print("等待新连接")13         data = conn.recv(1024)14         if not data:15             print("客户端已经断开连接")16             break17         print("开始发送数据")18         cmd_res = os.popen(data.decode()).read() #接受字符串，读取字符串19         if len(cmd_res) == 0:20             cmd_res = 'cmd has no input...'21         print("发送长度",len(cmd_res))22         conn.send(str(len(cmd_res.encode("utf-8"))).encode("utf-8"))23         print("执行指令", data)24         conn.send(cmd_res.encode("utf-8"))25         print("发送数据完成")26         print(cmd_res)
